ecumene

a portion of the earth;s surface that has ALWAYS been occupied by human settlements.

arable land

land suited for agriculture.

physiological density

the number of people supported by a unit arable land.

agricultural density

ratio of farmers to amount of arable land.

crude birth rate [cbr]
crude death rate [cdr]

the amount of people born each year for 1000 people.

ex: 20 CBR means twenty are born for every thousand people in thatarea.

same goes for crude death rate.

natural increase rate.
[NIR]

the percentage of population growth each year. it is calculated by take Crude Birth and Death rates and putting them in percentages then taking Crude Birth Rate minues the Crude Death rate percenatges.

natural= meaning it excludes migration! only births!

doubling time

number of years it takes to double the current population.

total fertility rate

geogrphers use TFR to measure the number of births in a society, basically the number of children a women will have during her fertility years.

what are the total fertility rates in the world?

three if the whole world is avraged.

six in african countries.

less then two in european countries.

infant mortality rate

annual number of deaths of infants under one year of age, compared ot the onest hat survive.

NOT A PERCENTAGE. just a number from one thousand, just olike crude birth and deaths.

explain stage one of population growth.

stage one [low growth]
most people during this stage depend on hunting and gathering, and birth death rates are scattered. During the beginning of time, many countries were stage one, but now none exist.

explain stage two of population growth.

stage two (high growth)
started at AD 1750, ten times faster then ever before.

during this stage the birthrate remains the same, but the death rate plummets.

what helped increase population numbers in "stage one" countries?

the agricultural revolution.

what caused countries to enter "stage two" of population growth?

the industrial revolution.

what was the Industrial Revolution?

happened after 1750. and increase of industry, such as steamboats trains and so, that made countries much wealthier, and in general heled increase the amount of health supplies and stuff, therefore people lived longer.

what was the Medical Revolution that helped the rest of the world enter Stage Two circa 1950?

when medical supplies from america and europe made it to less developed countries across the world.

explain stage three of population growth.

stage three [moderate growth]

a country goes from stage two to stage three when the crude birth rate drops significantly. The birth rate was falling in stage two, but now is falling much clower now then in stage two.

so, even though its dropping, the country is still populating because the birth rate is still higher then the death rate.

why does the birthrate keep dropping in stage three?

because of a change in social customs. people live much much longer and have a much larger chance to survive, so there is no need to have many children since each one has a huge surival chance.

also manuy more people during stage three now live in cities, and not farms, so there is no need for physical help anymore.

also since more people live in the city, there is no longer SPACE for large families.

explain stage four of population growth.

stage four [low growth]

this happens when the birthrate drops so low that its almost equals the rate of death, so population rates start to approach zero.
